We were all suddenly disconnected from our wifi yesterday. Saw the sign on my laptop saying no internet access, so, I restarted our router waited for it, then back to normal or so we thought, after that sudden disconnection none of us could connect to our wifi unless we're beside the router itself. I'm pretty sure nothing's wrong with our phones and laptops cause we can connect only you have to be close to the router. If you move about 10-15 feet, i guess, you start losing connection. We can still detect the signal on our devices/gadgets but all it does is connecting and connecting and never connects really. I did everything I could as far as my knowledge of this stuff can go. Restarted, Changed Channels, Changed SSID, Changed Passwords, I even had to reset it and nothing happened. Any advice?
